How to check that a document is really indexed?

Does someone know how to check if a document is well indexed after an update with Solr ?

I've tried to read the response after calling the add() method of SolrServer as below but it doesn't seem to work :

SolrInputDocument doc = new SolrInputDocument();
/*
 * Processing on document to add fields ...
 */
UpdateResponse response = server.add(doc);


if(response.getStatus()==0){
System.out.println("File Added");
}
else{
System.out.println("Error when Adding File");
}

In the javadoc, there is no way to know what returns the add() method. Does it always return 0 ? In this case, what is the best way to check that a file is well indexed after an update ?

Thank

Solution

  • You need to perform a commit to be able to see the documents added.
    Add will simply add the document to the Index.
    However, the document is still not returned as search result unless you commit.
    When you are indexing documents to solr none of the changes (add/delete/update) you make will appear until you run the commit command. 

    A commit operation makes index changes visible to new search requests.

    Also check for Soft commits which will perform in a more performant manner.
